Performs a simple check for the features of the IEEE standard.
void pslachkieee (MKL_INT *isieee , float *rmax , float *rmin );
void pdlachkieee (MKL_INT *isieee , float *rmax , float *rmin );
The p?lachkieeefunction performs a simple check to make sure that the features of the IEEE standard are implemented. In some implementations, p?lachkieee may not return.
This is a ScaLAPACK internal function and arguments are not checked for unreasonable values.
(local).
The overflow threshold(= ?lamch ('O')).

The underflow threshold(= ?lamch ('U')).
(local).
On exit, isieee = 1 implies that all the features of the IEEE standard that we rely on are implemented. On exit, isieee = 0 implies that some the features of the IEEE standard that we rely on are missing.
